Contained within this report are a series of case study field observations of selected retail design projects utilizing natural daylighting. Followed by the investigation and laboratory testing of three alternate roof fenestration patterns applicable to the least effective design. A description of the investigation procedure, a tabulation of all research findings and a section of concluding observations serve to round out this study. All of this done in an effort to prove that there exists a positive relationship between the effective incorporation of daylighting and owner/user satisfaction with the retail building type. / Master of Architecture
